Names the color of their class

Q u o t e:
This might sound ridiculous but, I put this setting on to where every name in the chat box is the color of their class. I need help finding out where it is in interface to change it. Please Help!

also, you know how you click on a character and next to your name at the top left of the screen if their name? Well, theres a setting where it shows who they clicked on, I need help finding that too.

Please help!!

I can't help you with the second question (sorry) but the first one is fairly easy. Right click on the chat tab (i.e., General) and click "Options". You can disable the class colors there.
